We are the Technolomies.

Veronica, the last Technolomy, has her birthplace listed as London, a city in our world, and the description of technolomies says that they were very scientifically/technologically advanced compared to the people from the more recent ages—kind of like, well, our world.

The backstory of this game is a possible Bad Future of Azur Lane if the latter's Muse System became prominent.

The conversion of emotional energy into physical energy may have snowballed beyond the Kansen's control.

Kaede's regrets contributed to the Contractual Purity image that is expected of the Priestess of Amatsu role, either by reinforcing the image or by leading to it being made.

When she gives Sakuya the Fire Score, she also asks her to "save his soul"; it's implied that Xeno was more important to her than Elcrest, and thus her request was for Xeno's soul to be saved. The fact that she introduced herself as "a former Priestess" instead of something like "the first Priestess" means the role predated even her, so the fact that she calls Sakuya her descendant opens two hypotheses:

• If a pure image already existed to be maintained, then Kaede's tragic bond with Xeno only added more fuel to its continued existence.
• If the image didn't already exist, then Kaede probably never fell in love again for the rest of her life, which became the basis for the image (out of respect, caution, or whatever else).
